CROSS-BEARER.

Specification of Letters Patent.

Patented Jan. 9, 1906.

Application led July 7, 1905. Serial No. 268,610.

1'0 mit r11/tom, t may concer it' Be it known that I, ALLEN E. OSTRANDER, a citizen of the United States, residing at Paterson, Passaic county, New Jersey, have in vented a certain new and useful Improvement in Cross-Bearers, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure I is a top plan view of a cross-bearer constructed in accordance with my invention. Fig. 2 is an elevational view of the crossbearer- Fig. 3 is a sectional view on the line 3 3 of Fig. 2, and Fig. 4 is a sectional view on the line 4 l of Fig. 2.

This invention relates to cross-bearers, and one of the objects is to provide a cross-bearer which will be light, durable, and strong and well adapted to transfer the strains at the sides of the car to the center sills.

In the form illustrated in the drawings, l indicates the center sill, consisting of two members, each of which is formed of a vertical web having an outwardly-projecting flange 2. These upper flanges 2 constitute the upper chords of what might properly be termed a plate-girder, the lower chord of each plate-girder being made up of two angles 3 and 4, secured on the respective sides of the web and having oppositely-disposed Hanges. Interposed between the members of the center sill is a filler comprising two plates 5, placed together, each plate having top and bottom flanges and side flanges, the side flanges being secured to the webs of the center-sill members and the top flange being secured to a top cover-plate 6, while the bottom flange is secured to the inwardly-projecting horizontal flanges 3 of the lower chord members. Projecting outwardly from each centersill member are parallel web members 7 and S, arranged back to back and flanged on all edges. The web members 7 and 8 have their flanges disposed in directions Opposite to each other, and they are secured to the webs of the center sill and to the channel side sills 9. A flat tensionmember lO is riveted to and passes over the cover-plate and extends nearly to the side sill. This tension member' is also riveted to the oppositely-disposed flanges of the respective members 7 and S, and a pressed or rolled bracket 11 is secured 'to each center-sill member, said brackets comprising channels approximately U-shaped in cross-section, having outwardlydisposed flanges 12 and 13, which are riveted to the outwardly-disposed bottom flanges of the members 7 and S. The end flanges 14 of the brackets Il are continuations of the flanges 1.2 and 13 and are fastened to the center-sill members by rivets, which pass through the webs of the center-sill members and through the side flanges of the plates 5.

It will be observed that the brackets 11 are wider at the middle portion of the crossbearer than at the ends and gradually diminish in width toward the side sills. This is done for the reason that it is believed that the greatest strain will be toward the center, and therefore the brackets are made heavier thereabout to resist this excess strain.

It will be observed that the corners of the web members 7 are cut out, so that said members will be secured beneath the top flanges of the center-sill members and be confined between the inwardly-projecting flanges of the side sills, while the tops of the web members are flush with the top cover-plates. One reason for this is to add rigidity to the cross-bearer and provide neat and conven ient forms of connections,

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a cross-bearer for cars, the combination with a center sill, oppositely-flanged web members carried by the center sill and arranged in pairs back to back, a tension member connected to the upper flanges of the web members, and U shaped brackets whose flanges are connected to the bottom Hanges of the web members substantially as described.

2. In a cross-bearer for cars, the combination with a center sill, pairs of web members secured to the respective outer sides of the center sill,and a pressed-steel bracketlcon'necting the respective web members of each pair to the respective webs of the center-sill member, substantially as described.

3. In a cross-bearer for railway-cars, the combination with center-sill members spaced apart, a filler between the center-sill mem- IOO y scribed.

4. In a cross-bearer for cars, the combination with a center sill, pairs of web members secured to and projecting from opposite sides of the center sill, and a channeled pressed-steel bracket secured to the bottom of each pair of web members the inner ends of lsaid brackets being of greatest dimensions and abutting the center sill, from which point they gradually diminish in width toward the outer ends of said web members; substantially as described.

5. In a cross-bearer for cars, the combination with a center sill, pairs of web members connected to the outer sides of the center sill and having their bottom edges below the neutral axis of the center sill, and pressedsteel brackets secured to the bottoms of said pairs of web members to connect the adjacent members together, said brackets being secured to the sides of the center sill and having outstanding channeled portions; substantially as described.

6. In a cross-bearer for cars, the combination of center-sill members spaced apart and having outwardly-proj ecting integral anges, pairs of web members connected to the center-sill members and having oppositely-disposed top flanges secured to the under sides of the top flanges of the center-sill members, channel-brackets substantially U sha e in cross-section secured to the bottoms o said web members and connecting them together in pairs, the inner ends of said brackets abutting the center-sill members, and a tension member secured to the top flanges of said pairs of web members and passing over the center-sill members; substantially as described.

7. In a cross-bearer for cars, the combination of center-sill members spaced apart and having outwardly-projecting integral flanges,

pairs of web members connected to the cen'- l ter-sill members and having oppositely-disposed top flanges secured to the under sides of the top anges of the center sill, channelbrackets secured to the bottoms of said web members and connecting them together in pairs, and a straight flat tension member secured to the tops of said pairs of web members and passing over the center sill substantially as described.

8. The combination with a center sill having a diaphragm-filler comprising two webs arranged back to back and having oppositelydisposed langes connected to the center-sill members, said filler being of a height equal to the height of the center sill, a continuous cover-plate forthe center sill and connected to said filler, pairs of web members connected to the outer sides of said center sill and having outwardly-disposed flanges, channel side sills having inwardly-disposed flanges between which the outwardly-disposed flanges of the last-named web members are confined,

and top and bottom members connecting the outwardly-disposed flanges of the respective last-named web members substantially as described.

9. In a cross-bearer for cars, the combination of center-sill members spaced apart and having outwardly-proj ecting integral flanges, web members connected to the center-sill members and having top and bottom flanges, said web members terminating short of the bottom flanges of the center-sill members, and pressed-steel brackets secured to the outer sides of the webs of the center-sill members and to the bottoms of the rst-mentioned web members, said brackets being wider at their ends near the center sill than at their ends near the side sills of the car, and said brackets being above the lower edges of the center sill substantially as described.

In testimony whereof I hereunto a'lflX my signature, in the presence of two witnesses, this 27th day of June, 1905.

ALLEN E. OSTRANDER.
